D-Cut Tool
Helical machining for any holes!
- Special cutting-edge design enables helical machining, suitable for multi-product production.
- Applicable to various hole diameters
- 20% reduction in power consumption due to low cutting resistance
- Reduced spindle power for downsizing
“Amazing Ideas / Facts!”
Because of its helical machining, the D-Cut Tool can be used for various hole diameters.
High-speed machining with the most suitable cutting-edge (material).
Multi-edges + its unique edge run-out adjustment mechanism enable low cutting resistance.
Reduced spindle load results in spindle downsizing (e.g. from conventional roughing Bo equipment #50 to #40!).
POINT!
Helical machining to unify toolsExcellent !
Reduction of cutting resistance (torque)Good !
Reduction of power usageGood !
Background / Point for Development
Background
- Increasing needs for multi-product production (at manufacturing sites).
- Work pieces with different diameters require each different tools which increase the need for further investments.
Point for Development
- With “D-cut tool”, various different cutting diameters can be processed with just one tool.
- The unique cutting-edge design & edge run-out adjustment mechanism enable low-resistance machining, which results in ‘cost reduction’ and ‘equipment downsizing’.
